Chronic pain, characterized by persistent discomfort lasting beyond three to six months, can stem from various sources such as injuries, arthritis, fibromyalgia, or neuropathy. Unlike acute pain, which serves as a warning signal of tissue damage, chronic pain persists long after the injury has healed, often becoming a debilitating condition in itself. It can manifest in various forms, ranging from dull and achy to sharp and stabbing pain, and may be accompanied by additional symptoms such as fatigue, sleep disturbances, and mood changes.
The transition from acute to chronic pain involves complex interactions between biological, psychological, and social factors. While acute pain typically resolves as tissues heal, chronic pain can persist due to alterations in the nervous system, including sensitization of pain pathways and maladaptive neuroplastic changes. These neurobiological mechanisms contribute to the amplification and prolongation of pain signals, leading to a persistent state of discomfort and dysfunction.
In understanding chronic pain, it is essential to adopt a biopsychosocial model that recognizes the interplay between biological, psychological, and social factors in shaping pain experiences and treatment outcomes.
